Answer:

45.6 x 10^3

Step-by-step explanation:

76 can be expressed as 7.6 x 10^1.

Now, you can multiply the two values together.

7.6 x 6.0 is 45.6.

Then, add the two exponents together:

1 + 2 = 3

45.6 x 10^3

Answer:

Answer:

111.75 degrees

Step-by-step explanation:

EDF = cos^-1((b²+c²-a²)/2bc)

EDF = cos^-1((10.4²+19.6²-13.2²)/2(10.4)(19.6))

EDF = 111.75 degrees

Answer:

Step-by-step explanation:

Circumference = 2 π r

100 =  2 π r

r = 100 / 2π

= 50/π

So the area = π r^2

=  π * (50/π)^2

= 2500/π

= 795.8 yd^2.

Answer:

  7/2 ≤ x < 4

Step-by-step explanation:

When an increasing function is applied to both sides of an inequality, their order does not change. We can solve the given inequality as though the square root symbol were not present.

__

  5 -x > 2x -7

  12 > 3x . . . . . add x+7

  4 > x

The domain of f(x) requires that its argument be non-negative.

  5 -x ≥ 0   ⇒   x ≤ 5

  2x -7 ≥ 0   ⇒   x ≥ 7/2

Together with the domain restriction on f(x), the solution to the inequality is ...

  7/2 ≤ x < 4

Answer:

y=4x+4

Step-by-step explanation:

using y=mx+b, y is y since we are writing a function. 4 would be the slope, as that is added per minute, so that takes the place of m, and x stays the same, which leaves b, the y intercept, to be 4. this is because the barrel already had 4 gallons inside before.

Answer:

14th term

Step-by-step explanation:

12÷10 = 1.2

14.4÷12 = 1.2

17.28÷14.4 = 1.2

Then it’s a geometric sequence of first term ‘V₀=10’ and common ration ‘q = 1.2’

We call it (Vn)

The general term of the sequence:

Vn = V₀×qⁿ⁻¹ = 10×(1.2)ⁿ⁻¹

To determine the term at which the sequence exceeds 100 we have to solve the equation:

Vn ≥ 100

⇔ 10×(1.2)ⁿ⁻¹ ≥ 100

⇔ (1.2)ⁿ⁻¹ ≥ 100/10

⇔ (1.2)ⁿ⁻¹ ≥ 10

⇔ ln(1.2)ⁿ⁻¹ ≥ ln(10)

⇔ (n-1)×ln(1.2) ≥ ln(10)

[tex]\Longleftrightarrow n-1\geq\frac{ln10}{ln1.2}[/tex]

[tex]\Longleftrightarrow n-1\geq12.6\\\Longleftrightarrow n\geq13.6\\\Longrightarrow n=14[/tex]

Verification:

[tex]V_{14}=10\times \left( 1.2\right)^{14-1} =106.993205379072[/tex]

Step-by-step explanation:

optically, they are congruent.

so, it must be a reflection followed by a translation.

there is no 90° rotation. and the result cannot be created only by a reflection.

Answer:

Somewhere between 12 and 13, perhaps 12.25

Step-by-step explanation:

This is a (rather) simple explanation:

Look for 2 square numbers that are either side of 150

In this case, it is 144 and 169

The square root of 144 is 12 and the square root of 169 is 13

Therefore we can estimate that the square root of 150 is somewhere between 12 and 13.

As 150 is a lot closer to 144 to 169, I would estimate around 12.25 but you do not need an exact value :)

Step-by-step explanation:

your a. is wrong.

so, we need to do both.

a.

you did not really read carefully. DE = 4x and not 4.

DE = 4x does not mean x = 4. absolutely not.

so, you cannot just use x=4 in the first triangle.

but you are right, AB and DE correlate between the 2 congruent triangles.

therefore

3x + 6 = 4x

6 = x

so, AB = 3x + 6 = 3×6 + 6 = 18 + 6 = 24 ft

b.

congruent means that the sides and the angles are the same between the 2 triangles.

so,

6y + 12 = 8y + 2

12 = 2y + 2

10 = 2y

y = 5

so, the angle EDF is

8y + 2 = 8×5 + 2 = 40 + 2 = 42°

An expression is defined as a set of numbers, variables, and mathematical operations. The value of x is 3.48.

In mathematics, an expression is defined as a set of numbers, variables, and mathematical operations formed according to rules dependent on the context.

The solution of the expression (x+3)²=41 can be found as shown below,

(x+3)²=42

(x+3)=√42

x+3=6.48

x = 3.48

Hence, the value of x is 3.48.

The value for c is 36 which completes the square for the quadratic x² + 12x + c.

The polynomial having a degree of 2 is termed as the quadratic equation.It means that the equation will have the maximum power of 2.

Here we have the equation

=x²+12x+c

=x^2+12x+36

=x^2+6x+6x+36

=x(x+6)+6(x+6)

=(x+6)(x+6

=(x+6)²

hence value for c is 36 which completes the square for the quadratic x² + 12x + c.

Step-by-step explanation:

In the question, it is given that a sphere has a radius of 10 cm and we have to find the volume of the sphere.

To Find the volume of the cone, we must know this formula :

[tex]\\{\longrightarrow{ \qquad{\underline{\boxed {\pmb{\frak { Volume_{(sphere) }= \dfrac{4}{3} \: \pi {r}^{3}}}}}}}} \\ \\[/tex]

Now, we will substitute the values in the formula :

[tex]\\{\longrightarrow{ \qquad{ {\pmb{\sf { Volume_{(sphere) }= \dfrac{4}{3} \: \times 3.14 \times {(10)}^{3}}}}}}} \\ \\[/tex]

[tex]\\{\longrightarrow{ \qquad{ {\pmb{\sf { Volume_{(sphere) }= \dfrac{4}{3} \: \times 3.14 \times 1000}}}}}} \\ \\[/tex]

[tex]\\{\longrightarrow{ \qquad{ {\pmb{\sf { Volume_{(sphere) }= \dfrac{4}{3} \: \times 3140}}}}}} \\ \\[/tex]

[tex]\\{\longrightarrow{ \qquad{ {\pmb{\sf { Volume_{(sphere) }= \dfrac{4 \times 3140}{3} }}}}}} \\ \\[/tex]

To Find :

Solution :

As we know that volume of sphere is calculated by the formula :

Here,

Putting the values in the formula,

>> V = (4 / 3) × (22 / 7) × (10)³

>> V = (4 / 3) × (22 / 7) × (10 × 10 × 10)

>> V = (4 / 3) × (22 / 7) × (10 × 100)

>> V = (4 / 3) × (22 / 7) × 1000

>> V = 4 × 22 × 1000 / 3 × 7

>> V = 88 × 1000 / 3 × 7

>> V = 88000 / 3 × 7

>> V = 88000 / 21

>> V = 4190.47 cm³
